Check if the result is ok? IN
Yes>go to Step 8.
NO>replace the pre-heater DI
8. Check the intake manifold pressure sensor and its relevant circuit.
a. Check the inlet manifold pressure sensor and its relevant circuit. (refer to “Chapter DI Diagnosis-Diagnosis EG
of Engine Electric Control Fault-Fault of inlet manifold pressure/temperature sensor”)
Check if the result is ok? TR
Yes>go to Step 9.
No>check and repair relevant fault or replace the inlet manifold pressure sensor or its relevant harness. AX
